(这是一条买家关于"Material certification"的询盘信息,来自第108届中国广交会。)Inquiry Message (询盘信息) Material certification My name is paul Kelly, I am a contractor in Washington DC. My sign supplier is VH Sign Co. in upper Marlboro MD. VH Sign gave me submittal information for a Federal Highway project my company is getting ready to begin. FHWA wants a material certification stating that the material complies with ASTM D 4956. On the material certification sheet I received from VH Sign had this information in the item section (6061-T6 and QQ-A-250/11). The material was for aluminum sheeting Is it possible that US Standard Sign Co. could provide me this certification.
